其他摘要	本论文由两个单元组成，第一部分主要对中国云南轿子雪山自然保护区的昆虫资源分布、物种组成及生物多样性变化做了系统的研究探讨。第二部分是对中国齿颚卷叶象甲科(Rhynchitidae)的绿卷象族的分类系统及生物学进行了初步探讨。轿子雪山是距离昆明最近的自然保护区，并是少数著名的低纬度高海拔雪山之一。轿子雪山自然保护区的生态平衡影响着整个昆明地区的生态环境。但是对于此保护区的生物资源及多样性方面研究至今仍缺乏。作者于2006年8月至2007年8月对云南轿子雪山自然保护区昆虫资源进行了进一步摸底调查，并以地表甲虫为主要研究对象对其物种组成及生物多样性季节变化进行了连续跟踪调查。调查结果如下：1，共获得昆虫标本3725头，分别隶属于14目76科385种。经物种鉴定及对记录资料的进一步整理，得到轿子雪山自然保护区昆虫名录12目72科327种。2，通过对4种典型微环境样地(草地、灌丛、林地以及农田生态系统）的三次跟踪连续调查，共获得标本2451头，分别隶属于24科。其中步甲科(Carabidae)为优势类群，占总数的62.10%；隐翅虫科(Staphylinidae)其次，占12.77% 。可能由于海拔、气温等因素影响，该地区昆虫活动高峰期较短。3，通过对4种典型微生态环境中地表甲虫的生物多样性的比较，表明不同生境内甲虫的多样性指数存在动态变化，在不同生境片区内甲虫存在迁移活动，甲虫多在灌丛中越冬，并随季节及食物源迁移。卷叶象甲绿卷象族(Byctiscini)隶属于鞘翅目(Coleoptera)齿颚卷象科(Rhynchitidae)。以其独特的繁育后代方式——筑造多叶摇篮而闻名。其主要危害杨、苹果、梨、桦、盐肤木等许多重要经济树木。本文根据对文献资料的归纳整理和对现有昆虫标本的检视，对中国齿鄂卷象科(Rhynchitidae)的绿卷象族昆虫进行了较详细的分类系统学研究。共记述了绿卷象族卷叶象甲5属(Byctiscus、Aspidobyctiscus、Byctiscidius、Listrobyctiscus、Baikovius)43种，其中包括1中国新纪录种(Byctiscu regularis)。作者对本族昆虫的生物学及地理分布做了概括性描述，结果显示此族昆虫以东洋区为多数(48.84%)，古北区其次(34.88%)，东洋-古北共有种则占9.30%。此外，根据文献记述及标本检视，纠正一处物种记录错误，并针对部分物种编写了检索表。; This dissertation was composed with two units. The first unit was about the insect species composition and biodiversity variation in Jiaozi Natural Reserve, Yunnan, China. And the second unit was about the taxonomic study of tribe Byctiscini (Coleoptera: Rhynchitidae) in China. Jiaozi Mountain, the nearest natural reserve away from Kunming, was one of the famous low-latitude-jokuls. The environmental balance in this area affected the whole Kunming area. Former researchers had done some primary studies on the species compostion in this area; however, data about biodiversity in Jiaozi Natural Reserve were still unknown. This study was aimed to make further study on the insect composition and biodiversity, so as to provide detailed research data for area conservation and developing. The study was executed during August, 2006 to August, 2007; and Ground-dwelling beetle communities were used to evaluate the seasonal diversity variation in Jiaozi Natural Reserve. The results showed that: 1) Totaly 3725 individuals were collected, which belonged to 14 orders, 76 families and 385 species. According to the specimen identification and paper record, 327 species, which belonged to 12 orders, 72 families, were listed distributing in Jiaozi Natural Reserve. 2) Through the three-month study (May, June, August in 2007) in 4 typical microhabitats (grassland, shrub, coniferous forest and farmland), 2451 beetles which belonged to 24 families were collected and analyzed. The Family Carabidae was the dominant group, which accounted for 62.10% of total individual number; the second common group was Staphylinidae (12.77% in total). It indicated that the beetles’ activeness period last short due to the high altitude and low temperature. 3) By comparing the biodiversity indices of 4 microhabitats, it was found that there were migrating activities among different sites. It indicated that beetles over-wintered in shrubs and migrated with the season variation. The beetles’ migrating activities probably accorded with the food source. Tribe Byctiscini (Coleoptera: Rhynchitidae), so-called rolling-leaf weevils, was characterized by its unique breeding pattern: rolling leaves into cradles and laying eggs inside. Many of the beetles fed on young leaves, and their host could be apple tree, pear tree and birch, to name a few. In the present dissertation, 43 species of Chinese Byctiscini, which belonged to 5 genera, were studied, according to the specimen examination and reference. Of them, the species Byctiscu regularis was newly recored in China. The species fauna was studied, and the results showed that of all the species, 48.84% belonged to the Oriental Realm, 34.88% belonged to the Palaearctic Realm, 9.30% belonged to both Oriental and Palaearctic Realm. In addition, a record error was corrected. The writer found that the Byctiscus lacuaipennis Jekel in genus Byctiscus and the Aspidobyctiscus lacunipennis (Jekel) in genus Aspidobyctiscus were the same species. The error must be due to transcription mistakes by former taxonomists. According to the morphologic characters, the species was corrected into Aspidobyctiscus lacunipennis (Jekel). Key to genera and species of some insects were provided, too.
